Putting "DRK" back in DRK

[Satarn]

I could see DRK doing 1/2 of the astrologian dps with those changes.

Well, looks like yours is already doing about that, so I suppose it makes no difference. : )

You are effectively decreasing DRK dps by around 37%.

As mentioned, the potencies are mostly meant as a representation. That said, I would be most grateful if you provided theory crafting and simulations behind your conclusion, so that we can make adjustments based on them!
